Note: Because of the difficulty of removing the LCD panels, cleaning the
LCD panels is beyond the scope of the Limited Servicer Program for all
other models included in this addendum.

Notes:

1. The safety and various description sections must be read in the Main Limited

Servicer Maintenance Manual (part code SM-LCD) before attempting any
procedures outlined in this addendum.

2. The maintenance procedures for the XV-H37VUA, XV-H37VUA(P) are

identical to the XG-E1100U. Therefore, please refer to the Main Limited
Servicer Maintenance Manual when maintaining the XV-H37VUA.

HOW TO CONVERGE THE LCD PANELS

For the models XG-NV1U, XG-E1200U, PG-D100U, XG-E3000U,
XG-NV2U, XG-NV3XU, XG-NV3XB, and XG-E3500U

Tools and equipment needed:

• Pattern Generator that can produce a crosshatch pattern (grid pattern)

• Eccentric Cam Adjustment Wrench. (Sharp Part # 9DASPN-XGNV1U)

• L-shaped Hex Wrench (Sharp part # 9EQLNC-XGNV1U)

• Philips Screwdriver

NOTE: Confirm focus before performing the convergence procedure. If pixels are
in focus in one area of the screen and indistinguishable in another area, the
projector is out of focus. The focus alignment procedure is beyond the scope of the
limited maintenance program.

Step Procedure Ref. #

1. Checking
convergence.

Refer to the safety notes on page S-1 of the Main Limited
Servicer Maintenance Manual before attempting to converge
the panels.

1. Connect a pattern generator to the video or RGB (when
applicable ) input terminals.

2. Output a crosshatch signal from the pattern generator.

3. Turn on the projector.

4. Mentally divide the screen into fourths both horizontally
and vertically. Imagine the center four squares as the A zone
and the outer one fourth (all around the outside edge) as the B
zone. Look at the grids to determine if the convergence is off.
You should see only white grid lines on the screen ( a white
line is the product of separate red, green, and blue lines
“added together,” or converged over the same area ). If the
red or blue lines are offset from the green lines ( either
up/down or left/right ), the convergence is off. The green

panel is fixed, so mechanical adjustment isn’t possible. If
any adjustments to the red or blue panels are necessary,
use green as the reference. If the unit is converged to within

one pixel in the A zone and one and a half pixels in the B
zone the unit is converged within specification and adjustment
is not required.

2. Removal of
body panels.

3. Adjustment
of the blue
panel.

1. To remove the cabinet, refer to the service manual for the
specific model.

1. Supply the projector with a blue and green crosshatch

signal from the pattern generator (on most video signal
generators, it is possible to remove one or more of the 3
colors making up the crosshatch signal. In this case red
must be removed. To do this refer to the instructions for
the pattern generator).

2. Use the L-shaped hex wrench to loosen the two hex screws

labeled “Lock Screw” in fig. 1.
Be sure to leave the lock screws tight enough so that when

an adjustment is made, the panel will stay in that position
until the lock screws are fully tightened after the
completion of all adjustments.

3. Use the eccentric cam wrench to adjust the Y axis (up and

down).

fig. 1

fig. 1

4. Use the eccentric cam wrench to adjust the X axis (side to

side).

5. Use the eccentric cam wrench to adjust the θZ axis
(tilt).

6. When the blue image is converged within specifications to
the green panel, tighten the two lock screws to secure the
adjustments.

NOTE: Tightening the screws may cause mis-convergence.
If this happens, readjust the affected panel.

HOW TO CHANGE THE LAMP ASSEMBLY

For The Models PG-D100U and XG-NV1U

Step Procedure Ref. #

1. Removal of
the old Lamp
Assembly.

2. Installing
the new Lamp
Assembly.

Refer to safety notes on page S-1 in the Main Limited
Servicer Maintenance Manual before attempting to change the
lamp

1. Remove the lamp cover.

2. Remove the screws securing the lamp assembly.

3. Pull the lamp assembly out of the projector.

Safety notes: Be sure to wear Safety Glasses when
removing the lamp. Do not attempt to remove the lamp
assembly until the projector has had an ample amount of
time to cool down.( 1 hour. )
After removing the lamp assembly, do not look at the
actual lamp.
Place the lamp assembly face down. This is necessary
because the metal halide lamp is pressurized and could
explode causing injury.

1. Insert the new assembly by pushing on it until it fits snugly
into the Lamp Well.

2. Install the screws into the same holes as the original lamp
assembly.

Note: Be sure the lamp cover is installed correctly or the
projector will not operate due to the safety switch not
being activated.

4. To reset the lamp timer, press and hold down the Enter,
Adjust Down, and Adjust Right Keys, then apply power to the
unit with the Main Power Switch on the side of the projector.
The projector should power on and display “0000H” on the
screen.

Lamp replacement is complete.
